Bin Li, Xiao-yan Tang, Jian Wei Lv · 2005
Web services are emerging as a dominant paradigm for constructing and composing distributed business applications and enabling enterprise-wide interoperability. A critical factor to the overall utility of web services composition is a flexible services discovery mechanism. The goal of this paper is to propose an agent-based approach to web services discovery. Firstly, an agent-based framework for web services composition is presented. Next, web services QoS model and description are introduced and an algorithm of selecting services from the perspective of composition is given. Finally, web services discovery agent is designed and its implementation based on JADE platform is presented in detail.
